L’età dei diritti al tempo del Covid-19: alcune riflessioni sull’incidenza della pandemia nella tutela interna e internazionale dei diritti fondament…

2020

L’età dei diritti rappresenta uno dei punti più alti dell’evoluzione della civiltà giuridica occidentale: dopo l’affermazione dello Stato liberale di diritto con le libertà negative e la successiva affermazione dello Stato sociale con i diritti in positivo (diritti sociali), soprattutto l'istituzione dell’Onu ha determinato la cd. internazionalizzazione dei diritti fondamentali dell’uomo, con una progressiva erosione dela sovranità statale in questa materia, ad opera di molte convenzioni internazionali a carattere universale e regionale, tra cui la CEDU. Ad oggi, la convivenza tra le libertà in negativo (tra cui la libertà personale, la libertà di riunione, la libertà di movimento) e i cd d…

AMMORTIZZATORI SOCIALI E NUOVE PROSPETTIVE DI WELFARE

In linea con la costruzione di un Modello sociale europeo e con i principi di flexicurity e lotta all’esclusione sociale elaborati nel quadro della Strategia Europa 2020, lo studio ripercorre le tappe dell’auspicato processo di razionalizzazione/universalizzazione del sistema degli ammortizzatori sociali in Italia, al fine di conciliare le istanze di flessibilità del mercato del lavoro con un incremento della sicurezza sociale e dell’occupabilità. In particolare, si analizzano le rilevanti modifiche introdotte dalla legge n. 92 del 2012 (cd. Riforma Fornero), nonché quelle proposte, a distanza di neanche due anni, nell’ennesimo percorso di riforma prefigurato all’interno del cd. Jobs Act , …

Kinetics of phase separation in thin films: Lattice versus continuum models for solid binary mixtures

2008

A description of phase separation kinetics for solid binary (A,B) mixtures in thin film geometry based on the Kawasaki spin-exchange kinetic Ising model is presented in a discrete lattice molecular field formulation. It is shown that the model describes the interplay of wetting layer formation and lateral phase separation, which leads to a characteristic domain size $\ell(t)$ in the directions parallel to the confining walls that grows according to the Lifshitz-Slyozov $t^{1/3}$ law with time $t$ after the quench. Near the critical point of the model, the description is shown to be equivalent to the standard treatments based on Ginzburg-Landau models. Unlike the latter, the present treatmen…

Domestic violence in Africa: a glance through the DHS survey

2022

Recent data states that 33 per cent of women in Sub-Saharan Africa are survivors of domestic violence. This work aims at assessing the association between women’s characteristics, their environment, and their history of violence in fifteen African countries. Three kinds of violence were explored: physical, emotional and sexual, each one exerted by the current partner. The data are from Demographic and Health Survey, in which a special module assessed domestic violence in female respondents. Using three independent logistic regression models, we found that witnessing violence of any kind has an effect on having a violent relationship, and while female empowerment is not protective, partners …

Study of quantitative and qualitative variations in essential oils of Sicilian oregano biotypes

2015

Essential oil (EO) was extracted using hydrodistillation from samples of Origanum vulgare subspecies hirtum (Link) Ietswaart, gathered from the wild in various parts of Sicily, Italy; GC-FID and GC-MS analyses were subsequently performed. The aim of the study was to analyze the relationship between essential oil yields and the geographical distribution of oregano wild populations based on variations in environmental factors as collection sites. Moreover, the purpose was to group Origanum vulgare subspecies hirtum biotypes according to the chemical composition of the EO. The seven principal components in the EO was thymol (24.0–54.4%), γ-terpinene (9.8–30.5%), ρ-cymene (5.2–18.7%), α-terpine…

Univariate and multivariate properties of wind velocity time series

2009

We analyze the time series of hourly average wind speeds measured at 29 different stations located in Sicily, a region with a complex morphology. The investigation, performed from the univariate as well as the multivariate point of view, evidences that the statistical properties of wind at the single sites have features that are not reproduced by standard models and, thus, require specific modeling. Moreover, the synchronous evolution of wind velocity presents a cluster structure, obtained with different algorithms, that persists in the standard deviation too.

BROILER CHICKENS AND THEIR HEALTH STATUS IN FARM: WINE WASTE, AN ADDED VALUE ON FEEDING

2023

Various key economic sectors of the National and Sicilian economy, in addition to contributing to the economic growth also cause a considerable production of waste which today are a problem both for companies then for the environment. For this reason, there is considerable interest in this waste and in the possibility of their reuse to extract bioactive molecules with added value, all in accordance with the objectives of the Blue Economy. In this regard, it has already been demonstrated that from the production waste of various economic sectors it is possible to obtain bioactive molecules with anticancer, antimicrobial, cosmetic, antioxidant and nutraceutical properties (Mauro et al., 2022)…

Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks

2016

In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to select multiple relays using the orthogonal matching pursuit algorithm and outperform state-of-the-art techniques in terms of outage probability and computation complexity. To reduce the amount of collected channel state information (CSI), we propose a limited-feedback scheme where only a limited number of relays feedback their CSI. Furthermore, a detailed performance-complexity tradeoff investigation is conducted for the different studied techniques and verified by Monte …

Energy Efficient Optimization for Wireless Virtualized Small Cell Networks With Large-Scale Multiple Antenna

2017

Wireless network virtualization is envisioned as a promising framework to provide efficient and customized services for next-generation wireless networks. In wireless virtualized networks (WVNs), limited radio resources are shared among different services providers for providing services to different users with heterogeneous demands. In this paper, we propose a resource allocation scheme for an orthogonal frequency division multiplexing-based WVN, where one small cell base station equipped with a large number of antennas serves the users with different service requirements. In particular, with the objective to obtain the energy efficiency in the uplink, a joint power, subcarrier, and antenn…

”Ei elämääni lomia mahtunut.” – Naisten muistelukerrontaa palkkatyöstä talvi- ja jatkosotien ja jälleenrakennuksen aikana

2014

My doctoral dissertation examines women’s memory narratives of paid labour during the Winter War (1939–1940) and the Continuation War (1941–1945, including the Lapland War) and in the years of rebuilding in Finland until early 1950s. As an ethnologist, I am interested in the personal level of everyday life and experiences of work. My main interest lies in the meanings women give to paid labour. The focus is on memory narratives, and I am reaching and I aim to bring to light the meanings given to work: what did paid labour mean for women during the war and the time of rebuilding and how do they tell about it decades afterwards? I analyse, for example, the effect of the war on women’s work ex…
